Td'ZtZZ whor ra'it 'n'tay concern: p Beit known that I, GEORGE G.Sermon- ,DER," a citizen offthe United States, residing "atrWashington,in the District of Columbia, havein'vented new and useful Improvementsin Brakes'for AerialNe'vigation, of which the following. isaspecification. 7

This invention "has relation to brakes adapted to be used in aerialtransportation i0 systemsg These brakes are located at the stationsalong the line ofthe aerial system "land are soconstru'oted as toautomatically stop all motors or" cars-passing through the station, orthe ylm'ay be so set as not to inig 'te'rfere with or stop motors. Aterminal buffer or brake is also; provided, which is adapted to stop themotors or cars at the t erninal' stations. The braking devices at thefistations n ay beoperated to release'the 1110- .26 tors and attachmentsat any desired time.-

. i Intheaccompanying drawings, Figure 1 is 'a side elevationof thebrake. Fig. 2 is an i end elevationof the mks.- Fig.3 is a longitudinalsectionalview of one of the members I Fig.4 isa sectional view of aterminal butler. Fig. 5 is a perspective view of a modified form of oneofthe arms of the brake. Fig'ifi isa'tr'ansverse sectional view ofone ofthe arms, showing the means 0 for pivotally attaching the same to itssupport. Fig. 7 is a'side elevation oft-he pivotal support forsaidarins, and Fig. 8'i's a perspec- ,ti've view of a band-spring usedin the brake.

f As above stated, a checking or braking de.

3 5 vice is located ateach station. It will be observed thatthereceptaole 1 of the carrier is cylindrical in shape and pointed atits ends.

"The said checking or braking device is adapted to receive and; operateupon said recepta- 'Thechecking orbraking device consists of a'series ofbrakes, all being similar in construction, but gradually increasing indegree of braking strength. Each individual brake consistsof ajnumber ofarms 2, pivot- 5 "arranged substantially parallel to each otherahdalinostdescribe a circle in cross-section,-

.surroundthe opposite ends of the arms 2. v5

adapted to receive the'poirited end of the-rearm-support 3, as shown inFig. 7.

Said'arms are the braking device, and is adaptedto'hold' the ends of thearms 2, around which it passes, in toward eachother, and the tongs 5 Thetongs are pivoted together at 6. The shaft 7 passes between the lowerends of the tongs .5, and an eccentric 8 is located on the shaft 7.between the lower ends of each set of tongsf The end of the shaft 7 isprovided with a crank 9, to the end of which is ivoted the pitrnan 10,which is also attache [to the operating-lever 11. At terminal stations,addition to the checkingxor braking devices ,abovedescribed, terminalbuffers are pro' -v'ided. Said buifers consist' of an air-cylin-.'de1112. (see Fig. 4,)which is provided at one end With'the aperture 13.The piston 14 is locatedin the cylinder IZ and is normally held againstthe cylinder-head byjthe coil spring The piston-rod '16 passes aroundthe head 5f the cylinder 14'and is provided at its outer end with a socket 17, Which'is ceptacle 1. L Y 5 The arms 2, are preferably made ofwood or other equivalent. materialwhich' oflers sufiicient friction tothe receptacle .1, but" does not: wear the same. Each said armthroughout its lengthdescribes a sinusoidal orcoinpound curve bowingoutward at its middle In the form of arm as shown at Fig. 5 the bearing18 is located on the rear edge thereof and is provided with aremoyablesection. The said'hearing 18 receives the spindle portion 8 of thesupport 3-. The blocks 32 are located at the ends of the spindles 3 and:properly space the arms 2 apart. The uprights 19 support the pivotal 4 v9 The operation of the invention isas follows: The motor carrying thereceptacle 1 is started upon its journey along the cable or traokwayprovided for that purpose, and when it ar-- rives at a stationthecurrent is cut or? by any suitable means, (not shown in the drawings)but the motorcontinues to travel by reason the ends'of' the arms' 2,surrounded by the iii checking or braking devices, which-are normallysettoe-ngage the sides of the recep'ta- .cle -1 and'offerfriction-contact therewith, it being understood that the ,'tens'ion ofthe first' spring 4 is less thanthat ofthe other springsand that thetension; of the said springs gradually increases", :Thus the innersidesof the-arms 2 bear against sides of the receptacle 1 and it is broil ofrest, -'ll 1e' operator thus swln 11, Which ifc'auses theshaft 7;;to

' 'artiiil ,lotation, and the-flecceh rice 8, bears 1g "against "the?lower ends 'of the tongs 5,, Force thesaid lower-ends apart and contractthe npper endszs, the same. This-presses ton s; inj,'- and consequentlythe ends of the sai arms under the springs 4 are forced out thereceptacle 1. is released, and it inay moved through 'the'checking orbraking devicea where it maybeunloaded and resided. Should itnotbe'intended to have its journey;- At terminal stations the end of thereceptacle 1 enters'the recess 17 and the :piston 16' moved back andcompresses the -air'inth ylinder '121and forces the same out==graduallythrough the aperture 13, it

being understood that'before-the end of the receptacle '1 engages thesocket l7that the said receptacle has passed through the'checking orbraking device, asabove described.- The-said checking or braking devicesare located under the trackway or cable upon which the cars. or motortravel.
